An at-home finger-prick test measuring morning cortisol, a hormone commonly used as a marker of stress. Suited to a quick standalone check on cortisol levels.
1 biomarker as listed by YorkTest.
The Stress (Cortisol) Test measures cortisol, commonly referred to as the body's stress hormone, from a sample taken in the early morning. YorkTest positions it for people wanting to check whether elevated cortisol might be affecting their stress levels, immunity or general health.
Within its cortisol test comparison group, its £41 price is tied with Forth's Cortisol Home Blood Test Kit as the cheapest of the five named peers, £4 below Medichecks' Cortisol Blood Test and Blue Horizon Medicals' Cortisol Blood - 9am test, both around £45, and considerably below Better2Know's Cortisol Test at £195, though Better2Know's cheaper Cortisol Home Test Kit is only £14 more at £55.
It scores well for Value for money, sitting exactly at the group median, and for Trust signals, reflecting YorkTest's Trustpilot rating of 4.8 from 3,257 reviews, its UKAS-accredited lab, and 44 years of trading. As a single-marker test, its Clinical depth score reflects that depth isn't the point of this comparison group; most named peers also test cortisol alone. It scores lower for Results and follow-up because results are not reviewed by a doctor as standard.
This suits people who want a quick, standalone check on morning cortisol without paying for a wider hormone panel, at the joint-lowest price in our comparison group. If you'd rather order from a different provider at the same price, Forth's Cortisol Home Blood Test Kit is also £41. It is not the right choice if you want cortisol tested alongside other hormones in one panel, or if you want a doctor to review your results as standard.
You take an at-home finger-prick blood sample in the early morning, when cortisol levels are typically measured, and return it to YorkTest's laboratory. Results are provided as traffic-light values with supporting lifestyle guidance, delivered within a stated 7 days. Doctor review is not included as standard.
Tied with Forth as the cheapest named test in its comparison group, YorkTest's Stress (Cortisol) Test measures early morning cortisol for £41. It is £4 cheaper than Medichecks' equivalent test and far cheaper than Better2Know's £195 Cortisol Test. Results are not reviewed by a doctor as standard.
